IMPROVEMENT IN N-OZZLES FOR OIL-CANS.

Specification forming part of Letters Patent No. 113,137, dated March 28, 1871.

I, JABEz A. BosTWIoK, of the city, county, and State of New York, have invented an Improved Nozzle and Valve Gap or Tap for Oil- Gans and other Vessels, of which the following is a specification:

N atnrc cmd Objects of thc Invention.

My invention relates to the formation of 011e or more discharge-apertures in an ordinary cap for the nozzle of an oil-can, and to the combination therewith of a valve, which may be made.to bear upon a ange or rim encircling the opening in the nozzle, so as to cover and close said opening at pleasure.

Description of the Accompanying Drawing.

General Description.

A is a nozzle, struck-up in the usual Inanner, of sheet metal, and provided with a hanged rim, t, (by means whereof it is secured over the mouth or opening of an oil-can or other vessel, 13,) and with a screw-thread cut or formed eXteriorly around its periphery, as shown in Fig. 1, so that the valve-capv may be screwed thereon.

The top of the nozzle is left closed or unbroken when manufactured; but it is deeply scored on top with a circular groove, c, (see Fig. 1,) much smaller in diameter than the cumscribed by said groove, may be very readily detached with the blade of a pen-knife, or by a sharp blow thereon, leaving in the top of the nozzle a central opening, w, Fig. 2, encircled by a at rim or iiange, d. (See Figs. l, 2, and 3.)

E is a plain cap, of a diameter to fit very closely over and screw down accurately upon the nozzle.

F F are apertures pierced in the top or rim of the cap at diametrically opposite points.

G is a screw, screwing centrally through the top ot' the cap E, which'is either made thicker and heavier for this purpose, or is fitted with a nut secured upon the under side thereof.

To the lower end of this screw G is secured a valve, H, formed of a metallic cup-shaped disk, on, soldered or otherwise secured to the end of the screw, in combination with a packing of leather, a, placed within the recess of said disk m, and confined by the rim thereof.

When the nozzle A, as first manufactured, is soldered over the mouth of the can, the can is thereby hermetically sealed. It is, however, readily opened by cutting or striking out the central piece, s.

The valve-cap E screws down over said nozl zle A, and when thus placed thereon its valve H will cover the opening w in the nozzle, and when pressed down by its screw Gr will bear closely upon the surrounding flange d, and thus perfectly close and seal said opening.

Whenever it is desired to withdraw any portion ot' the contents of the can, it is only neeessary to unscrew and thus open the valve H, when the liquid may be readily poured out through either of the apertures F, the opposite aperture serving in such case as a vent.

The valve-cap may be secured upon the nozzle A by means of a pin on the nozzle and an oifset slot in the cap, forming a bayonetjoint,7 instead of by a screw, as illustrated; or it may be secured otherwise by any of the simple devices known to the art.

The valve H may be pressed down by means of a spring inserted within the cap, between the top thereof and the valve H, in which case a simple rod is substituted for the screw G.

I contemplate, also, operating the valve, when a spring is employed to close it, by means of a short lever projecting from the side of the cap, and pivote-d within the same, so as to bear upon the valve and the spring, to compress the latter and elevate the former. In this case the use of a rod or screw projecting through the top of the cap is dispensed with.

Although I contemplate the use of all these equivalent devices for operating -the valve H, I prefer the use of a screw, G, as described.

In this my invention I combine the utmost cheapness (for its three simple parts are all `mede and fitted together at an extremely 10W in said. cap and opereterl by al screw, Gr, t

oost) with perfect durability and efficiency. upon the lange of the nozzle and close the opening therein, as specified.
